Description

Technical Field

[0001] The utility model relates to the technical field of electric chain window openers, in particular to a stroke-adjustable electric chain window opener. Background Art

[0002] With the improvement of household living standards, there are more and more types and shapes of windows. With the increase in the number of people and the reduction in urban building area, most of the current buildings are high-rise, and the distance between buildings is also very close, which makes it difficult for residents on the lower floors to get light. The current building windows, especially some high-end buildings, large buildings such as airports, sports centers, industrial plants, etc., are based on the needs of lighting, ventilation, environmental protection and full use of green sources. The window sashes are generally made larger and higher to allow more sunlight to penetrate the windows into the house. Therefore, in order to better meet the needs of opening and closing windows and the safety of opening windows, window openers are widely used in the market.

[0003] During the use of the existing electric chain window opener, since a part of the chain is exposed to the outside, the outer wall of the chain is prone to accumulate dust and stains. The existing window opener is not convenient for cleaning the dust on the chain when closing the window, and the service life is easily reduced over a long period of time. Therefore, we propose a stroke-adjustable electric chain window opener to solve the above problems. Utility Model Content
